This is definitely odd. At some point we noticed a particular pop up window appeared during the startup, but for some reason it didn't appear at the front. Instead it was spawned under the splash window. This bug should have been fixed already, though. If this is case, you might be able to simply hit "enter" to okay the dialog if it's there.

I get this sometimes as well. The blue splash screen sits there for about 10 minutes on 'Starting User Interface' before NIMate actually starts up. makes no difference if the sensor is plugged in or not.The only way I have found to fix it is to delete the plist file (i'm on Mac - i don't know where the license file is on Windows, but finding and deleting it might work) and then start up in trial mode, shut NIMate down, then re-enter my license next time it starts up.
